<p class="abstract"><strong>Background:</strong> Nasal obstruction is a highly prevalent problem caused by nasal septal deviation, with or without inferior turbinate hypertrophy. Nasal septoplasty and inferior turbinoplasty can improve the nasal airways. This study was designed to assess the efficacy of septoplasty alone and septoplasty with inferior turbinoplasty in cases having nasal septal deviation with inferior turbinate hypertrophy.</p><p class="abstract"><strong>Methods:</strong> A total 70 cases clinically diagnosed with the deviated nasal septum and inferior turbinate hypertrophy were randomly divided into two groups. Group 1 cases were under septoplasty alone and group 2 cases were under septoplasty with inferior turbinoplasty. Symptom improvement scores was assessed by sino nasal outcome test-20 (SNOT-20).  </p><p class="abstract"><strong>Results:</strong> The mean reduction symptom score of nasal obstruction was 1.73 in septoplasty with inferior turbinoplasty group, while in septoplasty group it was 1.06. The mean reduction symptom score in group 2 was statistically significant. All the cases of group 2 had adequate first pass diagnostic nasal endoscopy (DNE). While in group 1, majority cases had inadequate first pass DNE.  </p><p class="abstract"><strong>Conclusions:</strong> First pass DNE findings were favourable in the cases under septoplasty with inferior turbinoplasty Septoplasty with inferior turbinoplasty is effective in the reduction of nasal obstruction, facial pain, sleep difficulty, decrease in attentiveness and irritability in cases having deviated nasal septum with inferior turbinate hypertrophy.</p>

<p class="abstract"><strong>Background:</strong> Chronic rhinosinusitis (CRS) is a heterogeneous disorder leads to inflammation of nose and paranasal air sinuses. CRS affects quality of life of affected people, its diagnosis and management of is still a major challenge for the ENT specialists. CT scan and diagnostic nasal endoscopy of nose and paranasal sinuses plays an important role in the management of CRS.</p><p class="abstract"><strong>Methods:</strong> A total 42 cases with clinically diagnosed chronic rhinosinusitis between age group 2^nd -6^th decade were considered. All the participants underwent a systemic diagnostic nasal endoscopy and CT scan of nose and paranasal air sinuses before surgery.  </p><p class="abstract"><strong>Results:</strong> Nasal blockage/obstruction (95.2%), headache/facial pain (90.4%), nasal discharge (85.7%), sneezing (76.1%) are commonest symptoms. Diagnostic nasal endoscopy noted to be a sensitive investigation tool for the sphenoethmoid recess, hiatus semilunaris and frontal recess. The sensitivity of above parameters is 100%, 94.8% and 95.1% respectively whereas, specificity is 83.2%, 79.5% and 94.8%.</p><p class="abstract"><strong>Conclusions:</strong> Diagnostic nasal endoscopy findings and CT scan findings correlated very well with the operative findings. In few cases DNE could not visualize all the parameters due to anatomical deviations. But CT scan is a specific diagnostic tool which depicted all the parameters except maxillary sinus and its bony shell in very few cases.</p>
